Abstract
An endoscope, through which the interior of a body cavity can be observed, has an operation section and an insertion section. The proximal end of the insertion section is connected to the distal end of the operation section. A conduit-type guide fiber is coupled at one end to the distal end of the insertion section. The other end of the guide fiber is connected to the operation section. The guide fiber has meandering or looped portion for absorbing the stress applied to the fiber when the insertion section is bent. Therefore, there is no possibility that the guide fiber is broken. In addition, the insertion section has a sufficient flexibility.
